In-situ Monitoring System

Along with factory automation, there is an increasing need for sensor technology that can diagnose processes.
Existing optical sensor technology is suitable for dry etching equipment such as dry etcher, However CVD When applied to thin film deposition equipment, its use is limited due to issues such as decreased reliability due to the accumulation of chamber films.
HeMos is a product that compensates for these shortcomings. It can Quality prevention and preservation Through in-situ process monitoring and Through in-situ thickness monitoring It can contribute to replacement of thickness measurement, process control through ARS implementation, and improvement of thickness distribution.
